Title: Improvements in or relating to the mounting of objectives for use with cinematograph and like projectors
IPC: G03B5/04
Filed: 1933-03-29
Abstract: 397,418. Optical-projection apparatus. SOC. POUR L'EXPLOITATION DES BREVETS A. G. 1., 88, Rue des Dames, Paris. March 29, 1933, Nos. 9525 and 9526. Convention dates, April 9, 1932, and Oct. 21, 1932. [Class 97 (i).] In an objective mounting for a kinematagraph &c. projector, means are provided for varying the focal length of the objective to alter the size of the image, and simultaneousl y varying the inclination of the objective axis to the horizontal to such an extent that the lower edge of the image area remains at a fixed height on the screen. In the form shown, the objective 1, the focal length o f which can be varied by rotating the forward lens ring 1a, is mounted within a cylindrical casing 2 on which is rotatably mounted a ring 7 having a projection 8 engaging a pin 9 on the ring 1a. At its rear end the casing 2 is formed with bearing surfaces 10 engaged by screws 11, Fig. 7, carried by the support 12 secured to the projector. The member 12 has forwardly extending arms 13 between which is mounted a shaft 14 to which is secured a cam 15 and an arm 16. The cam engages a cage 20 having upwardly extending arms 21 carrying trunnions 22 engaging in the casing 2. A cable 17 connected at one end to the arm 16 passes round a groove 24 on the ring 7 and is secured at its other end to the ring. When the shaft 14 is rotated by the handle 18 the cable turns the ring 7 to alter the focal length of the objective and therefore the size of the projected image, and at the same time the cam 15 acting on the cage 20 causes the casing 2 to turn on the pivots 11 to maintain the lower edge of the image in a fixed position. A spring within the ring 7 effects the reverse rotation of the ring when the handle 18 is turned in the opposite direction. The objective 1 can be adjusted axially in the casing 2 to focus the image by means of an eccentric pin 3 engaging in the objective and rotatable by a head 3a. The pin is mounted in a carriage 4 which can be displaced axially along the casing by means of a nut 6.

Title: Improvements relating to rotary cutting and creasing presses
Inventor: CROPPER RONALD
IPC: B31B50/22
Filed: 1963-04-12
Abstract: 1,029,582. Creasing apparatus. ENGLISH SEWING COTTON CO. Ltd. July 10, 1964 [April 12, 1963], No. 9650/63. Heading B6J. [Also in Divisions B4 and B5] In a cylinder machine for producing creased and cut-out blanks for boxes &c., a tympan or complementary member to the cutting and creasing forme is made by attaching to the cylinder a steel sheet with a covering of force board or presspahn, taking an impression of the form on to the board by carbons, removing the sheet from the cylinder and attaching it to a similar cylinder 19, Figs. 4, 6, associated with devices for cutting grooves in the board where the creasing marks occur. The second cylinder comprises a number of rods 16 attached to end discs 17 and similar intermediate discs, the discs 17 having bearings mounted on frames 21. The cylinder 19 can be rotated by means of a hand wheel and can be locked in any circumferential position by means operated by a handle 22, Fig. 3. Brackets 25 attached to the frames 21 support a member 26 carrying adjustably a plate 27 with a chamfered straight edge 29 arranged to be parallel to the cylinder axis. A guide rail 31 is fixed to the plate 27. As shown, a portable rotary toothed cutter 33 with a flexible drive 34 is used for cutting the grooves, but a non-rotary cutter may be employed. For making a longitudinal groove, the cylinder 19 is rotated until the line of the groove is adjacent to the edge 29 and is then locked. The cutter is then placed on the plate 27 with a groove 35, Fig. 4, in its casing 36 engaging the rail 31 and the cutter 33 positioned just beyond the straight edge 29. The depth of cut is determined by a screw-adjusted member 38 abutting against the plate 27. For cutting the circumferential grooves, a plate 40, Fig. 6, curved to the cylinder periphery is provided, the plate having a circumferential rib 46 for engagement with the groove 35 of the cutter casing 36. A strip 42 attached to the plate 40 has a screw 43 which is engaged with the rail 31 and adjusted so that one edge of the plate 40 abuts against the edge 29. The parts 42, 40, 36 can be moved in the axial direction along the plate 27 until the cutter 33 is in position to cut a circumferential groove, whereupon the cylinder 19 is rotated to produce the groove. After the grooving has been completed, the surplus board around the edges corresponding to the shape of the blank is removed. The completed tympan is now ready for mounting on the cylinder of the cutting and creasing machine. The cutting and creasing forme may be mounted on a chase having threaded holes aligned with threaded holes in the machine bed for receiving securing screws, so that if the chase is detached from the bed it can be re-attached easily in correct alignment. Thus, during preparation of a tympan, its forme may also be removed from the machine, and another forme and tympan inserted so that the machine need not be idle during preparation of a tympan.

Title: Improvements in or relating to interference reduction in television
Inventor: DAVIES ERIC
IPC: H04B1/12
Filed: 1952-04-17
Abstract: 732,677. Correcting inductive disturbances. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Dec. 11, 1952 [April 17, 1952], No. 9724/52. Class 40 (4). [Also in Group XL (b)] A circuit arrangement for reducing or eliminating hum in a television signal circuit, for example the hum picked up in the outer screens of coaxial cables, comprises means for sampling the television signal at recurrent periods when picture information signals do not occur, i.e. the line blanking intervals, means for integrating the sampled signals to provide an integrated hum-correcting signal and means for utilizing said signal for opposing the hum interference in the circuit. In Fig. 5 the television signal passes through a channel comprising three amplifiers GA, V1, V2 and the D.C. component at the output is restored by a conventional clamp-type circuit D1, D2. In order to eliminate hum superimposed on the signal the output from the final stage F1 of amplifier V1 is applied through a buffer stage BF to a sampling stage 2 in the form of a gate which is opened under the control of pulses (a) applied to the suppressor. The pulses occur at line frequency and their timing is arranged so that gating occurs either during the " front porch " or the " back porch " or during the line synchronizing period. The signals at the input to stage 2 are arranged with the synchronizing signals in a positive direction and D.C. restoration is effected by current flow at the grid. Alternatively D.C. restoration may be effected to the "black" " level. Since the gating is effected when picture component signals are not present and the input is held at a fixed level the anode pulses across resistor 6 are proportional to the amplitude of the superposed hum. A linear relationship between the anode pulses and the input signal is ensured by a negative feed-back connection between the screen grid and control grid. The anode pulses are integrated by condenser 7 and the gating frequency component removed by filter 8, 81. The resulting hum-correcting signal is then applied through an adjustable phase-shifting circuit 9 to amplifying stage CV1-CV4. The output from CV2 is applied to oppose the hum at the input to amplifier V1 and a further reduction is effected by a connection from CV4 into the cathode circuit of the first stage in amplifier V2.
